HORSESHOE.

Specification of Letters Patent.

Patented July 24, 1906.

Application filed January 12. 1906- Serial No. 295.796.

To all whom it may concern: M;

Be it known that I, WILLIAM D; OBRIEN,

,a citizen of the United States, residing at Snow Shoe, in the county ofCenter and State of Pennsylvania, have invented certain new and usefulImprovements in Horseshoes; and

I do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to certain new and useful improvements inhorseshoes having asoft tread portion; and the special object of my saidinvention is to produce a shoe the soft tread portion of which may bereadily attached to and detached from the metal portion, but which willnot be liable to accidental displacement.

In order that my invention may be thoroughly understood, I have clearlyillustrated the same in the accompanying drawings, and a full and exactdescription thereof is contained in the annexed specification.

In the accompanying drawings, Figure 1 is a perspective view of myimproved shoe.

Fig. 2 is a perspective view of the metal portion thereof. Fig. 3 is aperspective view of the soft tread portion. Fig. 4 is a perspective viewof a portion of the core and clips. Fig. 5 is an enlarged sectional viewthrough the soft tread portion. Fig. 6 shows a slightly-mo dified formof core.

In the several views like letters of reference designate similar partsof my improved device.

A in the drawings designates the metal shoe portion of ordinary shapeand size and provided on its edges with the vertical grooves a, saidgrooves being wider at the back than at the front, forming the inclinedsides a.

0. represents screw-threaded orifices ex tending through the metal shoeportion and preferably located between the corresponding grooves on theinside and outside of the shoe.

B designates the core, having a series of enlarged portions b, saidenlarged portions being provided with the upwardly-extending portions 1)1), corresponding in shape to said grooves a and adapted to closely fittherein.

5 designates orifices located in the enlarged portions b and are adaptedto register with the orifices a in the metal shoe portion. C designatesthe soft tread portion molded onto said core B and provided with theorifices 0, adapted to register withthe holes b I and a said orificesbeing larger in diameter below the portions 1) than above.

D represents screws adapted to pass through the soft treadportion'C andengage the threaded orifices (L The heads d of said screws D are adaptedto be countersunk in the soft tread portion 0, as shown in Fig. 5, andbearing against the metal portions 1;.

. From the foregoing it is obvious that the soft tread portion may bereadily secured to the metal shoe portion after the same has beenfastened in the usual manner tothe hoof by first inserting theprojections 6 into the grooves a, which prevents the cushion fromslipping on the metal portion, and then inserting the screws D, turningthe same until the soft treadportion is tightly pressed against themetal portion. With this construction it is apparent that the cushionmay at any time be readily detached and a new one applied in its stead.

In Fig. 6 I have shown a slightly-modified form of core, which in thisinstance is not provided with the upwardly-extending portions 1), andtherefore when using such a construction it would be unnecessary toprovide grooves in the metal portion. With this exception this device issimilar to the one above described, and the manner of securing thecushion to the metal portion is substantially the same.

What I claim, and desire to secure by Letters Patent, is

1. In a horseshoe of the kind described, the combination with a metalportion provided with threaded orifices, of a soft tread portion havinga series of plates embedded therein and provided with orifices extendingthrough said plates and registering with said thread- 5 ed orifices insaid metal portion, said metal plates being provided withupwardly-extending arms adapted to engage the edges of said metalportion and screws adapted to be inserted through the orifices in saidsoft tread portion into said threaded 'orfices in said metal portion,the heads of said screws being countersunk in said soft tread portion,substantially as described.

2. In a horseshoe of the kind described, the combination with a metalportion provided with threaded orifices and on its edges with grooves,of a soft tread portion having a series of plates embedded therein andprovided with orifices extending through said plates 'jecting arms ofcorresponding shape to said as described.

'3. In a horseshoe of the kind described, the combination with a metalportion provided with threaded orifices and on its edges with grooves,said grooves being wider at the 5 back thanat the front, of a soft treadportion having a series of plates embedded therein and provided withorifices extending through said plates and registering with saidthreaded orifices in said metal portion, said metal plates beingprovided with upwardly-progrooves and adapted to fit therein and screwsadapted to be inserted through said orifices in said soft tread portioninto said threaded orifices of said metal plate, the heads of saidscrews being adapted to be countersunk in said soft tread portion,substantially as described.

4. In a horseshoe of the kind described, the combination with a metalportion provided with threaded orifices and on its edges with grooves,of a soft tread portion having a core provided with enlarged portionsembedded therein, and provided with orifices extending through saidenlarged portions of the core, and registering with said threadedorifices in said metal portion, said enlarged portions of said corebeing provided with upwardly-projecting arms adapted to fit into saidgrooves in said metal portion and screws adapted to be inserted throughthe orifices in said soft tread portion into said threaded orifices insaid metal portion, the heads of said screws being countersunk in saidsoft tread portion, substantially as described.

In testimony whereof I afiix my signature in the presence of twowitnesses.
